[BUG] Setuptools allow arbitrarily wrong configs in setup.cfg #4913
Description
The issue in #4910 unveiled something much deeper.
It seems that setuptools has been allowing arbitrary fields (like description_file described in #4910) in setup.cfg (possibly without a visible warning -- needs investigation)1.
Expected outcome
Setuptools should issue a deprecation warning when a invalid field in used in setup.cfg.

Funny thing is that issue [BUG] Version 78.0.1 breaks install of ansible-vault package #4910 always involves
description-file. I find it hard to believe that it is a coincidence, possibly many packages CTRC+C, CTRL+V the same config all over the place. ↩
